Title: Channel specification system
Inventor: SATOU MASAHIRO
IPC: H04B1/40
Filed: 1981-08-27
Abstract: PURPOSE:To correctly specify a frequency number which corresponds to a channel specified with a channel changeover switch, by setting the frequency number again when transition between transmission and reception occurs. CONSTITUTION:A transmission/reception state detector 5 generates and sends an output signal to a channel specifying code generator 2 on a change in state from transmission to reception or from reception to transmission. As a result, the channel specifying code generator 2 sends out a channel switching code specified with a channel changeover switch 1 not only when a power source is put to work and when a change in state occurs to the channel switch, but also when a state change between transmission and reception is generated. Then, data in a register 3 is set again, so every time the change in state between transmission and reception is generated, correct data is held in the register 3. Consequently, a programmable frequency divider 4 accurately sets a frequency number which corresponds to a channel specified with the channel changeover switch 1 invariably.

Filed: 1987-06-01
Abstract: PURPOSE:To average the number of result data held by cut ingots and to shorten an editing processing time by providing process for deciding the next data collection timing based on a casting speed. CONSTITUTION:The casting speed detected by a casting speed detector is taken in and checked periodically in a speed monitoring process 2.

These collected result data are stored in a result collection data file 5. Then the result data corresponding to cut ingots 8 is retrieved out of the file 5 in a cut result process 7 by a signal received from a cutting device 6. Thus a cut file 9 is obtained and the casting speeds are collected in a fixed cycle and compared with the constant of a stepped casting speed range decided previously. Then the start timing is decided for the process 3.
